Sunday afternoon at New York's Citi Field, and the stands are full to capacity. They're packed not with New York Mets fans, though. They're packed with 40,000 Ultra Orthodox Jews, there to attend a rally against the more nefarious aspects of the internet.

These amazing images, snapped by Getty photographer Mario Tama, capture the rally in full swing, as the all-male crowd listened to addresses warning against the potential dangers of social media, online pornography and other aspects of uncensored web use.

Don't get the idea it was a rally against the internet itself. The event couldn't have been organised without online correspondence, kosher apps (yes, they exist) were being advertised and those among the Orthodox Jewish community in New York who couldn't attend were able to watch events via webcast.
